 The quarry attracts divers from across the UK |
Police have named the man who died after a diving accident at a notorious quarry lake in north Wales. Jon Edward Hepherd, 53, from the Warrington in Cheshire, died last Friday after getting into difficulties at the disused Dorothea Quarry in the Nantlle Valley, Gwynedd.
The quarry lake - up to 300ft deep in places with a network of flooded tunnels and sheer drops - is a favourite training location for amateur divers from across the UK.
Its icy waters have claimed five lives in the past year and around 20 in the last 10 years.
Scores more have had lucky escapes and have needed to be rescued.
It is thought Mr Hepherd suffered a heart attack and was pronounced dead at the scene.
His companion suffered from the bends and was flown for treatment at a specialist decompression chamber on the Wirral.
It is believed he is also from the Warrington area.
Despite warnings from the quarry's owner, divers continue to travel from hundreds of miles away to train there.
